Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a steam/water separation device applied to a blower type dehydration system.

As is well known, for example, in a fabric vacuum dehydrator,
A vacuum pump (blower) is used to suck out the moisture contained in the fabric.

However, vacuum pumps other than water ring vacuum pumps are
Moisture in the inhaled air must be removed before pumping. In addition, water ring pumps also require chemical solutions, resin liquids for resin processing, etc. in order to save power, especially water, and eventually all vacuum pumps require the use of air-water separators. It has been pointed out. In order to prevent the liquid in the suction component from reaching the vacuum pump when the gas and water components are sucked in by a vacuum pump, conventionally a steam and water separation device has been installed in the path to separate the gas and liquid. is installed.

Conventionally, as this type of steam/water separation device, a Zyclone type device is often used. In this steam/water separator, a drainage pump is used to drain the separated liquid from a negative pressure container.

In this case, since the suction side is under negative pressure, suction becomes difficult, which often results in dry running or a small amount of drainage. Further, even if the liquid level of this device is controlled, the pump may seize or the like, resulting in considerable damage to the device.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a steam/water separator that separates the gas and liquid in the suction component before reaching the vacuum pump when the gas/water component is sucked by a vacuum pump. Instead of using a drainage pump to drain the liquid, the chamber through which the water passes can be switched to negative or positive pressure, making it more effective due to the water's own weight. An object of the present invention is to provide a steam/water separator that discharges water.

In order to achieve the above-mentioned object, the present invention specifically provides a separator including a steam/water component suction port, a gas discharge port connected to a blower, and a water discharge port for discharging separated moisture; Connected to the water outlet,
and a drain tank with a drain port at the lower end, the drain tank having:
It has an upper chamber, an intermediate chamber, and a lower chamber that communicate in the vertical direction through first and second communication openings each having an on-off valve, and each of the chambers communicates with each other through an air bypass passage. A solenoid valve is provided in the drain passageway to detect the amount of water supplied to the drainage tank and operate according to its output to selectively communicate the intermediate chamber with either the upper chamber or the lower chamber. Each of the on-off valves is characterized in that it closes due to a difference in pressure between adjacent chambers, and opens due to the weight of water when the pressure is the same.

On the other hand, the drain tank (3) in the steam-water separator (1) is connected to the lower end of the cyclone separator (2) via the water outlet (6) of the cyclone separator (2). . The drainage tank (3) basically includes an upper chamber (12), an intermediate chamber (13), and a lower chamber 04). The upper chamber (12) and the middle chamber 0

(19) has exactly the same configuration, and the axis (P)
It is rotatably supported around the shaft and has a counterway (C, W) at one end. The on-off valves (16) and (19) are adjusted to close due to the difference in pressure between adjacent chambers, and to open due to the weight of water accumulated in the upper chamber when the pressure is the same. On the other hand, each chamber (12) j (1B) + (14) is
On the outside thereof, they are communicated by an air bypass passage (21). The air bypass passage (21) includes an upper solenoid valve that opens and closes between the upper chamber (12) and the intermediate chamber 03), and an upper solenoid valve that opens and closes between the intermediate chamber θ3) and the lower chamber θ→. A lower solenoid valve is provided. The upper solenoid valve (c) and the lower solenoid valve (c) are set so that when either one is opened, the other closes simultaneously.

The opening/closing operations of the upper electromagnetic valve H and the lower electromagnetic valve (C) are switched according to the output of the detected water amount supplied to the waste water pI (3). As shown in FIG. 2, the means for detecting the amount of waste water supplied to the drainage tank (3)

249, (a). The water level detector (
C) is placed in the upper chamber 02), detects the water level in the upper chamber 02) at its upper limit, opens the upper solenoid valve (A), and closes the lower solenoid valve (A). In addition, the water level detector (c) is placed in the intermediate chamber 03),
detecting the water level in the intermediate chamber 03) at its upper limit;
Close the upper solenoid valve 0→ and open the lower solenoid valve (c).

As a means for detecting the amount of water supplied to the drainage tank (3), the upper and lower limits of the amount of water in the upper chamber (B) are detected in the upper chamber (02), and the upper and lower solenoid valves are activated. The valve (c) may be configured to open and close alternately.

On the other hand, a timer can be used as an output signal generating means for opening and closing the upper solenoid valve 0 and the lower solenoid valve (c). In this embodiment, the timer (2 o'clock, (c) calculates the water supplied to the upper chamber (b) and intermediate chamber 03) temporally, and operates after a predetermined period of time to output the water. The upper and lower solenoid valves are alternately opened and closed depending on the signal.

The operation mode of the steam/water separator of the present invention having the above structure will be explained. The operation of the device starts when the suction blower power supply and the water level detector switch power supply are turned on.

The steam and water components drawn by the suction blower are introduced into the cyclone separator (2) and separated into steam and water. The separated gas component is drawn by the blower 00) and discharged to the outside from the gas outlet (5). On the other hand, the separated water is discharged toward the upper chamber 02 of the drain tank (3) through the water outlet (6) of the separator (2).

During the period when water is discharged from the separator (2) to the upper chamber (12), the upper solenoid valve (231) is closed depending on the output of the water level detector, and on the contrary, the lower solenoid valve (231) is open. Therefore, the upper chamber (02) is directly connected to the blower and is in a negative pressure state, and the intermediate chamber (13) and the lower chamber (04) are connected to the lower chamber through the open lower solenoid valve (c). They are directly connected to the atmosphere through the atmosphere side exhaust port (EX) provided at θ4), and are in a positive pressure state. In this state, the on-off valve (16) is adjusted to open and close according to the pressure difference between each chamber.

Of α9), an on-off valve θ6) between one upper chamber (b) and an intermediate chamber θ3) is closed. Therefore, water discharged from the separator (2) accumulates in the upper chamber (b). Upper chamber (1
2) When the amount of water supplied reaches a predetermined amount, the upper chamber water level detector (c) is activated and outputs an electrical signal.

This output signal opens the upper solenoid valve H and closes the lower solenoid valve (A). By opening the upper solenoid valve H, the upper chamber (b) and the intermediate chamber 03) are connected to each other through the air bypass passage Q.

3) is ejected by free fall. At this time, since the lower solenoid valve (c) is closed, the intermediate chamber (1
3) has a negative pressure, while the lower chamber θ4) has a positive pressure, so the lower opening/closing valve (G) maintains the closed state, and the water discharged from the upper chamber (B) flows into the intermediate chamber. It accumulates in (13).

When the amount of water supplied to the intermediate chamber (13) reaches a predetermined amount, the intermediate chamber water level detector (2 koji) is activated and outputs an electric signal, thereby closing the upper solenoid valve (a). Open the lower solenoid valve.

Lower solenoid valve (air bypass passage 0 due to opening of 2 valves)
The intermediate chamber (13) and the lower chamber θ→ are directly connected to the atmosphere side exhaust port (EX) and have the same pressure in a positive pressure state, and the lower part opens and closes under the weight of the water supplied to the intermediate chamber 03). Valve 09)
open. Therefore, water flows from the middle chamber (13) to the lower chamber 0
Free fall towards →. At this time, since the upper solenoid valve (2) is closed, the intermediate chamber (I3) is under positive pressure, whereas the upper chamber (2) is under negative pressure, so the upper opening/closing valve (16 ) maintains a closed state, and the water discharged from the separator (2) begins to accumulate again in the upper chamber θ2),
Return to the initial state of the operating cycle of the device.

When the water level adjustment timer Q, (b) is used instead of the water level detector @→, (c), it operates in exactly the same cycle as described above. In other words, the water level adjustment timer (
2: In (c), the amount of water per unit time to be dehydrated from the material to be dehydrated is calculated in advance, and the amount of water per unit time is calculated in advance, and
) is detected over time, and a timer is activated to open and close the upper and lower solenoid valves () and (2).

According to the steam/water separator of the present invention having the above configuration, in a vacuum type dehydrator, when separating steam and water and sucking moisture, the vacuum pump mechanism and the drainage pump from the negative chamber are used to discharge the moisture. There is no need for . That is, the steam/water separation device of the present invention allows the water separated by the separator to pass through a drainage tank consisting of three chambers: an upper chamber, an intermediate chamber, and a lower chamber, and changes the pressure in the intermediate chamber to positive pressure and negative pressure. This system is designed to effectively drain water using the pressure difference between adjacent chambers and the weight of the water.1. It can be said that it is highly effective as an energy saving device.
